12 / 17Copyright 2010-2018 Honcell Energy. All Rights Reserved.©
14.2.3 Over-discharging
It should be noted that the cell would be at over-discharged state by its self-discharge characteristics in case
the cell is not used for long time. Over-discharging may cause loss of cell performances, characteristics or
battery functions. In order to prevent the cell over-discharging, the cell shall be charged periodically to
maintain between 3.6V and 3.9V. The charger shall be equipped with a device to prevent further discharging
exceeding cut-off voltage specified in this specification sheet. Also the charger shall be equipped with a device
to control the recharging procedures as follows:
a: The cell or battery pack shall start with a low current 0.1C as pre-charging before rapid charging starts.
b:The rapid charging shall be started after the (individual) cell voltage has been reached above 3.0V can be
determined with the use of an appropriate timer for pre-charging. In case the (individual) cell voltage does not
rise to 3.0V within the pre-charging time, then the charger shall have functions to stop further charging and
display the cell/pack is at abnormal state.
14.3 Protection Circuit Module(PCM)
The cell or battery pack shall be protected by PCM and have the functions of over charge, over discharge and
over current prevention to maintain safety and prevent significant deterioration of cell performances
14.3.1 Overcharging Prohibition:
Overcharging prevention function shall stop charging if any one of the cells of the battery pack reaches 4.20V.
14.3.2 Over-discharge Prohibition:
Over-discharging prevention function shall work to avoid further drop in cell voltage of 3.0V or less per cell in
any cell of the battery pack. It is recommended that the dissipation current of PCM shall be minimized to 0.5uA
or less with the over-discharge prevention. The protection function shall monitor each bank of the battery pack
and control the current all the time.
14.4 Storage
Keep the cells in half-charged state to help keep them fully charged or completely discharged. Put the cells in
cool and dry place when storing them. The cell shall be storied within -10ºC to 35ºC environmental condition. If
the cell has to be storied for a long time unused (over 3 months), need to activate the battery once every 3
months according to the following steps:
1) charge at 0.2C to 4.2V then rest 5 min.
2) discharge at 0.2C to 3.0V then rest 5 min.
3) then charge again at 0.2C to 3.9V
The voltage for a long time storage shall be 3.8V to 3.9V range. The environmental condition is preferred at
ambienttemperature 23±2 and relative humidity 65±20%.ºC
14.5 Handling of Cells
Since the Li-po cell is packed in soft package, which can be easily damaged by sharp edge parts such as
pins,needles and Ni-tabs, ect., comparing with metal can-cased LIB. To ensure its better performance, it's very
important to handle the battery carefully.
1) Avoid any short-circuit. It will cause the leads to get hot and lose electrical functions.
2) Soft package is easily damaged by sharp objects such as needles and knives. Avoid touching the cells with
sharpobjects when handling and storing.
3) Next to the leads is the sealed edge. Don't bend or fold the sealing edge as it is sensitive to movement.
4) Don't open the folded edge on the sides of the cell.
5) Don't bend the tabs as the tabs are sensitive.
13 / 17Copyright 2010-2018 Honcell Energy. All Rights Reserved.©
6) Avoid mechanical shock to the cells.
7) Don't put the cells into an oven, washing machine or any high-voltage container.
8) Don't use a charger without a safety certification. Use only a recommended charger.
9) You should immediately stop charging if the cell overheats, emits an odor, changes color, changes shape,
etc.
10) The children should be supervised by adults when using the batteries.
11) Before using batteries, please carefully read and understand the Handling Precautions and Safety
Guidelines.
12) Avoid electro-static discharge when using, charging, and storing cells.
13) Avoid putting the battery in contact with metal conductors such as neck chains, barrettes, or bolts, etc.
14) Don't use metal conductors to connect the positive and negative leads together.
15) Avoid errors during assembly by contacting the positive lead with the negative lead.
16) Keep away batteries from children.
17) The cells/batteries are requested to be stored within a proper temperature range specified in this
specifications.
18) Do not store batteries in a manner that allow terminals to short circuit.
19) Do not place batteries near heating sources, nor exposed to direct sunlight for long periods. Elevated
temperatures can result in reduced battery service life.
14.5.1 Soft Aluminum Foil
The soft aluminum packing foil is very easily damaged by sharp edge parts such as Ni-tabs, pins and needles.
1) Don't strike battery with any sharp edge parts.
2) Trim your nail or wear glove before taking battery.
3) Clean worktable to make sure no any sharp particle .
14.5.2 Sealed Edge
1) Sealing edge is very flimsy.
2) Don't bend or fold sealing edge.
14.5.3 Folding Edge
1) The folding edge is formed in battery process and passed all hermetic test.
2) Don't open or deform folding edge.
14.5.4 Tabs
1) The battery tabs are not so stubborn especially for aluminum tab.
2) Don't bend tab.

14.9 Recommended Notice:
1) Using cells on specified facilities only.
2) Using cells in normal ambient temperature range specified in this sheet, and at relative humidity 65±20%.
3) Using the cells, away from heat source. Don't let children play with cells. Don't drop cells. Charge cells with
specified charger.
4) Avoid the positive pole shortcutting with the negative one. Avoid the cells affected with damp.
5) Don't drop cell into the water or fire.
6) If the cell isn't used for a long time, please keep the cells in a half-charged state neither fully charged nor
completely discharged. Recharge the cells and use half of the power after 2-3 months. Store the cells in a cool
and dry place, this will protect the cell from damaging.
7) If any matters with this specification arises, it shall be revised by mutual agreements.
14.10 Warranty
Honcell warrants its battery to be free of defects in material and workmanship. Batteries are manufactured in
accordance with Honcell's specification. Honcell warrants only to the original user that all batteries will be free
of defects in material and workmanship for a period of twelve months. The applicable warranty period begins
from the date of shipping, or if no obvious evidence is available to state the shipping date, refer to the date
code on the product. In no case shall Honcell's liability with defects proven due to manufacturing process
instead of the customers abuse and/or misuse. Charges for correcting a defective battery will not be allowed
nor will Honcell accepts batteries returned for credit or exchange unless Honcell authorizes the correction or
return in written form. The warranty does not cover a battery reaching its normal end of life which may occur
prior to the warranty periods stated above. A Battery can deliver only a fixed number of usable amp-hours over
its lifetime and is considered to have reached its normal end of life if the application uses up all of these amp-
hours, regardless of the time the Battery has been in service.
